How to convert a char array back to a string?

Question

I have a char array:

char[] a = {'h', 'e', 'l', 'l', 'o', ' ', 'w', 'o', 'r', 'l', 'd'};

My current solution is to do

String b = new String(a);

But surely there is a better way of doing this?

Answer 1

Your solution is absolutely correct and very insignificant.

Note, however, that this is a highly unique place: Because String is managed especially in Java, even "foo" is a String. So they require a string into unique chars and join them back is not needed in normal code.

Examine this to C/C++ where "foo" you have a package of chars produced by a zero byte on one side and string on the additional side and many varieties between them due to legacy organizations.
